This Privacy Policy explains how Nivaar Tech Tools ("Nivaar", "we", "us") collects, uses, discloses, keeps and protects personal information when you use our website and services at nivaar.net (the "Services"). We are based in Ontario, Canada, and we handle personal information under Canada's Personal Information Protection and Electronic Documents Act (PIPEDA). Residents of British Columbia, Alberta and other provinces have equivalent rights under their provincial laws, and we honour them the same way.
Nivaar provides Nivaar Exam Prep, a study service with AI-drafted worked solutions and study guides for past Engineers and Geoscientists BC academic examinations. The owner of Nivaar is the privacy officer responsible for this policy and for answering your requests. Contact: support@nivaar.net. If you would rather write by post, email us and we will give you our mailing address.
We collect only what the Services need. We do not use analytics services, advertising networks or tracking cookies.
| Category | What | Why |
|---|---|---|
| Account information | Name, email address and the province or territory you live in; the optional organization and message you give when requesting an account; your password (held by Amazon Cognito, never visible to us); your role (customer or administrator) | To review your account request, create and secure your account, and sign you in |
| Purchases and access | Your Nivaar Pass (its length and end date, and the Stripe checkout references of each purchase), the disciplines and subjects you have unlocked, requests to unlock them, and a Stripe customer reference. Stripe collects your card details and billing address at checkout; we never see your card number. We read the billing address's province only to cancel a payment from Quebec, where the Pass is not sold, and we do not store the address. The province you choose before checkout is passed to Stripe with the purchase | To deliver what you bought, manage refunds, and keep the records the tax law requires |
| Study activity | Practice-quiz scores per sitting | To show your progress across devices |
| Licensing mark | Your email address, shown as a "Licensed to" mark on the pages you open | To discourage redistribution of licensed material |
| Support, error reports and feedback | Emails you send us and our replies. From the "Report an error" form on a solution page or guide: the page, your description, and your email only if you choose to give it. From the feedback form on the Contact page: your feedback, your email only if you choose to give it, and whether you ticked the box that lets us quote it (with the wording of that box). To stop abuse of these forms we count submissions per network address for two hours, using a hashed form of the address. As with every request, the address also appears in our server logs (kept 90 days); the text you send is not written to those logs | To help you, correct solutions, improve the site, and handle refunds and complaints. Only if you ticked the box: to quote your feedback on this site, without your name or email |
| Technical data | Server logs of requests to the Services (time, requested page, IP address, and your email when signed in) | To operate, secure and troubleshoot the Services |
We do not collect anything from you for the AI that drafts the solutions: the solutions are generated in advance and served as ordinary files, and your name, email and activity are never sent to an AI system.
The worked solutions are public: you can read them without an account, and we then collect only the technical data in Section 2. By creating an account you consent to the collection and use described in Section 2. Buying access adds the purchase records. You can withdraw consent at any time by deleting your account (Section 8); account features cannot be provided without an account.
We do not sell personal information, do not share it with advertisers, and do not send marketing or promotional bulk email.
We send transactional, service-related email only: account confirmations and temporary passwords, purchase receipts and access notices, refund confirmations, replies to your messages, security notices, and notices about changes to these terms that affect you. Every email identifies Nivaar as the sender with a working reply address. These messages are needed to operate your account, so they carry no marketing unsubscribe; you can stop all account email by deleting your account or by writing to support@nivaar.net. If we ever start a newsletter, it will be opt-in with a separate, unticked consent box and an unsubscribe link in every message, as Canada's anti-spam law requires.
The Services run on Amazon Web Services (AWS) in the United States (us-east-1). Your personal information is therefore stored and processed in the United States and may be subject to access by US authorities under US law. Our providers, each acting on our instructions under their own security and privacy commitments:
We do not disclose personal information to anyone else, except where the law requires it or to protect the Services against fraud or abuse.
We keep personal information only as long as it is needed for the purpose it was collected for, or as long as the law requires. Our schedule:
| Information | Kept | Reason |
|---|---|---|
| Account, purchases and quiz scores | While your account is active. Deleted when you delete your account. Accounts with no sign-in for 24 months are deleted after an email notice | Needed to provide the Services |
| Purchase and refund records (email, what you bought, amount, date) | 6 years after the end of the tax year of the purchase, in Stripe and in our records | Required by Canada's Income Tax Act |
| Pending account requests | 12 months | The purpose lapses |
| Server logs | 90 days | Security and troubleshooting |
| Support email, error reports and feedback | Support email: 2 years after the last message. Error reports and feedback: 2 years after we receive them. If you let us quote your feedback and we use a quote, we keep a copy of the quote and of your permission, without your name or email, while the quote is on the site | To handle follow-ups, corrections, refunds and complaints, and to show that a quote was given with permission |
| Records of any privacy breach | At least 24 months | Required by PIPEDA |
Data is encrypted in transit and at rest on AWS. The worked solutions are public pages; study guides and other paid material are served only to signed-in users with access, and every such request is re-checked against your account. We restrict internal access to personal information to what is needed to operate the Services, and we keep no copies on personal devices. If a breach of security involving your personal information creates a real risk of significant harm to you, we will notify you and report it to the Office of the Privacy Commissioner of Canada as soon as feasible, and we keep a record of every breach whether or not it is reported.
We use browser storage only to run the Services: sign-in tokens are kept in session storage and, by our sign-in library (Amazon Cognito), in local storage until you sign out; local storage also remembers preferences such as dark mode, keeps a copy of your quiz scores, and, if you have a Nivaar Pass, its end date, so that pages you read in that browser show no ads (it is removed when you sign out). We use no third-party advertising or tracking cookies and no analytics scripts. Fonts are loaded from Google Fonts, and the sign-in library (and, where needed, the maths renderer) from the jsDelivr content network; both may record your IP address when they load.
The Services are for engineering and geoscience licensure candidates and are intended for people aged 18 or over. We do not knowingly collect personal information from anyone under 18; if you believe we have, tell us and we will delete it.
We may update this policy. We will change the "Last updated" date above and, for changes that matter to you, notify you by email or a notice on the Services. We will not use your information for a materially new purpose without asking you first.
Privacy officer, Nivaar — support@nivaar.net — Ontario, Canada.
